IMPROVED GUDGEON FOR BOOMS.

Specification forming part of Letters Patent No. 66,633, dated July 9, 1867.

To all whom it 'may concern:

Be it known that I, NATHANIEL RoBBINs, Jr., of Rockport, in the county of Essex, in the State of Massachusetts, have invented Va new and Improved Connection or Gudgeon for Booms; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, and showing one application of my improvement on board vessels, in Which- Figure l` is a perspective View; Fig. 2, a horizontal view; and Fig. 3, a vertical section.

Similar letters refer to similar parts, as follows:

A, portion of mast, to which the boom is attached, B, lower end of boom; C, collar or span clasping the mast and forming a support for the socket D, piutle E, and universal joint F, which together form the gudgeon which I claim as my improvement. By this device, the friction usually attending the motion of a boom against a mast is very much lessened, and the strain brought upon the throat and jaws or piutle of a boom, as ordinarily arranged, by the tendency of a sail full in the wind to roll a boom over on its axis, is entirely avoided. i

By making the socket D and piutle E longer than would be otherwise necessary, I am enabled to give a vertical motion to the boom, which may at times be valuable. In construction I bring the weight of the boom upon the socket D, and not upon the piutle E.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The use of the socket D and the pintle E, as a bearing for a boom and connection with a mast, substantially as described.

2. The construction and arrangement of the boom-joint or connection, substantially as described.
